Telegram Security Guide for Iranian Users

Telegram is one of the most widely used communication platforms in Iran, serving not just as a messaging app but as a vital source of news and connection. However, its popularity makes it a primary target for the Islamic Republic's surveillance apparatus. Since the 2018 ban, accessing Telegram requires circumvention tools, introducing new attack vectors like insecure proxies and state-controlled "forked" versions of the app.

This guide outlines critical steps to secure your Telegram account and communications specifically against threats present in the Iranian digital landscape.

Critical Warning for Activists: Telegram Cloud Chats (the default chat) are not end-to-end encrypted. Telegram can technically access these messages if compelled by authorities or if their servers are compromised. For highly sensitive, high-risk communication, use Secret Chats or switch to Signal.

1. The Dangers of Third-Party Clients ("Forks")

In Iran, unofficial versions of Telegram (Forks) are heavily promoted because they often come with built-in proxies that bypass censorship without needing a separate VPN.

🚫 DO NOT USE:

• Telegram Talaei (Telegram Gold)
• Hotgram
• Mobogram
• Videogram
• Any "Anti-Filter" Telegram version

The Risk: Many of these applications are developed or controlled by Iranian intelligence agencies (such as the IRGC) or private companies cooperating with them. They can:

• Log your IP address and location.
• Access your contacts and files.
• Read your messages (bypassing encryption).
• Identify the administrators of anonymous channels.

✅ Solution: Only install the official Telegram application from the Google Play Store, Apple App Store, or telegram.org. Use a trusted VPN to access the service.

2. Proxies and Connection Security

Since Telegram is blocked, users must use a connection method to access it.

MTProto Proxies

While convenient, MTProto proxies are risky.

• Promoted Channels: Many free proxies force you to join "sponsor channels." These channels may distribute malware or state propaganda.
• Surveillance: Proxy owners can see your IP address and metadata (though not the content of messages if you use the official app). The regime has reportedly set up honeypot proxies to map user networks.

✅ Best Practice:

• Use a reputable, paid, or trusted VPN (like Mullvad, Proton VPN, or IVPN) that routes all your device traffic, rather than relying on Telegram-specific proxies.
• If you must use a proxy, use one from a trusted source (e.g., a friend running a private server) rather than random free proxies found in public channels.

3. Account Hardening

Enable Two-Step Verification (Cloud Password)

⚠️ Critical for Iranian Users: Iranian mobile operators (MCI, Irancell, RighTel) have a history of intercepting SMS verification codes to allow intelligence agents to hijack accounts.

1. Go to Settings > Privacy and Security > Two-Step Verification.
2. Set a strong password.
3. Recovery Email: Ensure your recovery email is secure and not accessible by anyone else. If your email is compromised, your Telegram account can be taken over.

Defense: If an agent intercepts your SMS code, they still cannot access your account without this second Cloud Password.

Hide Your Phone Number

Your phone number is a direct link to your real identity.

1. Go to Settings > Privacy and Security > Phone Number.
2. Who can see my phone number? → Select Nobody.
3. Who can find me by my number? → Select My Contacts (or Nobody if available/preferred to prevent random enumeration).

Active Sessions Check

State hackers often add a device to your account rather than changing the password, allowing them to spy silently.

1. Go to Settings > Devices (or Privacy and Security > Active Sessions).
2. Review the list regularly.
3. If you see an unknown device (e.g., a "Samsung" device when you only own "Xiaomi"), tap Terminate immediately and change your Two-Step Verification password.

4. Privacy & Anonymity Features

Disable "People Nearby"

This feature allows anyone close to you geographically to see your profile and distance. Security forces can use this to triangulate the location of protesters or gatherings.

• Ensure People Nearby is turned OFF.
• Revoke "Location" permission for Telegram in your phone's Android/iOS settings unless you are actively using live location with a trusted contact.

Disable Contact Syncing

Syncing contacts uploads your entire phone book to Telegram's servers. This helps the regime map social graphs (who knows whom).

1. Go to Settings > Privacy and Security > Data Settings.
2. Turn off Sync Contacts.
3. Tap Delete Synced Contacts to remove data already on the server.

Username Security

• Do not use a username that links to your real name or handles used on other public social media (like Instagram or Twitter/X).
• If you are an admin of a sensitive channel, use a dedicated, anonymous account (burner number) for administration, not your personal account.

5. Communication Security

Cloud Chats vs. Secret Chats

• Cloud Chats (Default): Encrypted between your device and Telegram's server, and between the server and the recipient. Telegram has the key and can technically read these.
• Secret Chats: End-to-End Encrypted (E2EE). Only you and the recipient have the keys. Telegram cannot read these.

✅ Recommendation for Activists: Always use Secret Chats for sensitive conversations.

1. Open the profile of the user.
2. Tap the "..." (three dots) or "More".
3. Select Start Secret Chat.

Disappearing Messages

In Secret Chats (and now Cloud Chats), set a self-destruct timer.

• In Secret Chat: Tap the clock icon in the text field and select a time (e.g., 1 minute).
• This ensures messages are deleted from both devices automatically.

6. Avoiding Behavioral Traps

Disable Link Previews

Link previews can leak your IP address to the website being previewed.

• Go to Settings > Privacy and Security > Data Settings and disable Link Previews (if available) or simply avoid generating them for sensitive links. Note: In some versions, this is handled under Secret Chats automatically, but be cautious sending links in groups.

Do Not Open Unknown Files

Malware masquerading as documents (PDF, Word) or Android APKs is a common method used by groups like "Charming Kitten" to infect devices.

• Never download an APK sent via Telegram.
• Verify the sender before opening any attachment.

"Saved Messages" as a Target

Many users use "Saved Messages" as personal cloud storage for photos and documents. Remember: If your account is compromised or your phone is seized and unlocked, everything in Saved Messages is accessible to the interrogator. Regularly clear sensitive data from this folder.
